c++ - Matching contours to level images - OpenCV -


is possible match & level contours in image? possibly symmetric matching? if so, matcher use purpose?

demonstration image:

problem

in image of lovely imac, can see images passed in unleveled. because took first image @ different height second image.. example:

(first image capture)                         (second image capture)

so, instead of matching features on image, wondering if opencv has feature matcher limit me match edges of 1 image ends, , other 1 begins. way, straighten them up.

what use:

  • bestof2nearestmatcher
  • gridadaptedfeaturedetector gfttdetector
  • siftdescriptorextractor
  • refining camera parameters based on features basic opencv sample

what hope result:

my target result align images in demonstration image above.

i kind of working on same issue. can surely limit feature points using mask. in case know there 50% overlap in adjacent images, have used features in later half (x > im.cols)of first image , initial half of second image(x < im.cols).you can make changes in matchers.cpp of stitching. eliminate chance of false matches.

but fail when there less or no feature points. suggest go line based stitching if aligning edges of object main concern.

line features in opencv3.0

amazon web services - S3 Pre-signed POST validate file type? -

i know it's possible put limit on file size content-length-range header. possible validate file type? https://docs.aws.amazon.com/amazons3/latest/dev/httppostforms.html#policyconditions i see there content-type header, if set say, audio/mp3 allow mp3 files , return error if file not mp3? i found previous question answers mention validating file size: s3 direct upload restricting file size , type you can specify content-type @ post request. you can specify @ signature, post must done content-type: { "expiration": "2007-12-01t12:00:00.000z", "conditions": [ {"acl": "public-read" }, {"bucket": "johnsmith" }, {"content-type: "audio/mp3"} ] } creating html form (using aws signature version 4) edit: @ previous question found, checking content-type.

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
